Contract
- getSideChannel creates a side channel instance supporting set, get, has, delete, and assert methods
- side channel stores and retrieves metadata for object keys without modifying the object itself
- side channel stores and retrieves metadata for primitive keys such as strings, numbers, and symbols
- side channel delete removes key-value associations and returns boolean status
- side channel assert verifies key existence and throws TypeError when key is not present
